Originally the X ACT dac was released by Musical Fidelity in their family of valve equipped audio gears assembled in nice and original cylindric cabinets.These were X LP phono preamplifier, headphone amplifier, etc and to provide valve output advantage for DACs in this series MF developed special valve output buffer known as X10D.The latter vas marketed by the company as “missign link” in between audio sources, like dac and amplifier. This approach was extremely successful, tube buffers are widely recognized to improve dac sonic performance significantly. Unfortunately X10d is quite rare now.Based on this original idea we decided to fit a valve buffer insde the X ACT dac as its cylindric cabinet was originally made for tube based gears an allow this technical approachGoal of this modification is to improve sonic performance of the X ACT dac with tube based output and make exactly as it was proposed originally by Musical Fidelity
Modifications
We fitted valve output stage based on 6J1 low noise pentodes. You can see design details on pictures.We did not change components is the original DAC board to keep the dac itself originaljust additional mimiature PCB with valve output stage is added. Its schematics corresponds to X10D.We supply extra powerful mains adaptor in leu of the original one. The extra power allows valve supply as well as improves sonic performance of the dac itself.
